Einstein-Podolsky-Rosen Steering for Mixed Entangled Coherent States
Entropy, 2021 By using the Born Markovian master equation, we study the relationship among the Einstein–Podolsky–Rosen (EPR) steering, Bell nonlocality, and quantum entanglement of entangled coherent states (ECSs) under decoherence.

Quantum analogues of Hardy's nonlocality paradox [PDF]
, 2011 Hardy's nonlocality is a "nonlocality proof without inequalities": it exemplifies that quantum correlations can be qualitatively stronger than classical correlations.

Causal hierarchy of multipartite Bell nonlocality [PDF]
Quantum, 2017 As with entanglement, different forms of Bell nonlocality arise in the multipartite scenario. These can be defined in terms of relaxations of the causal assumptions in local hidden-variable theories.

General Non-Markovian Quantum Dynamics
Entropy, 2021 A general approach to the construction of non-Markovian quantum theory is proposed. Non-Markovian equations for quantum observables and states are suggested by using general fractional calculus.

Decoherence-Induced Sudden Death of Entanglement and Bell Nonlocality
Photonics, 2022 Decoherence due to the unwanted interaction between a quantum system and environment leads to the degradation of quantum coherence. In particular, for an entangled state, decoherence makes a loss of entanglement and Bell nonlocality known as entanglement

Quantum Nonlocality for a Mixed Entangled Coherent State [PDF]
, 2001 Quantum nonlocality is tested for an entangled coherent state, interacting with a dissipative environment. A pure entangled coherent state violates Bell's inequality regardless of its coherent amplitude.

Quantum Nonlocality and Beyond: Limits from Nonlocal Computation [PDF]
Physical Review Letters, 2007 We address the problem of "nonlocal computation," in which separated parties must compute a function without any individual learning anything about the inputs. Surprisingly, entanglement provides no benefit over local classical strategies for such tasks, yet stronger nonlocal correlations allow perfect success.
